Trait Codec 

pub trait Codec {
    type Value;
    type Encoded: AsRef<[u8]>;

    // Required methods
    fn encode(d: &Self::Value) -> Option<Self::Encoded>;
    fn decode(bytes: &[u8]) -> Option<Self::Value>;
}

A trait that defines how types are decoded/encoded.

Required Associated Types

type Value

type Encoded: AsRef<[u8]>

Required Methods

fn encode(d: &Self::Value) -> Option<Self::Encoded>

fn decode(bytes: &[u8]) -> Option<Self::Value>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
